entity framework 6 - IManifestTokenResolver for Database First Model? -

we need option set providermanifesttoken in code database first model in order override value edmx, defaults "2012" sql server 2012 in our particular case.

what we've tried far: described in this post decorated our context class dbconfigurationtype attribute, our derived class looks same in post.

internal sealed class mydbconfiguration : dbconfiguration {    public mydbconfiguration()    {       //this.adddependencyresolver(new singletondependencyresolver<imanifesttokenresolver>(new manifesttokenservice()));        this.setmanifesttokenresolver(new manifesttokenservice());    } } 

as can see, tried 2 different things here, adddependencyresolver , setmanifesttokenresolver.

when start application program execution enters constructor of mydbconfiguration - , that's it, dependency resolver itself

internal sealed class manifesttokenservice : imanifesttokenresolver {    private const string sqlservermanifesttoken = @"2005";     private static readonly imanifesttokenresolver defaultmanifesttokenresolver = new defaultmanifesttokenresolver();     /// <inheritdoc />    public string resolvemanifesttoken(dbconnection connection)    {       if (connection sqlconnection)       {          return sqlservermanifesttoken;       }        return defaultmanifesttokenresolver.resolvemanifesttoken(connection);    } } 

is never invoked seems we've reached dead end here. has had same problem , found solution?
